Does Sybase provide an IIOP gateway for applet -to- EAServer
communication? I understand that (most) IIOP gateway products use a
proprietary protocol for applet -to- proxy chatter, therefore requiring
the client to use an ORB specific to the gateway; of course I would like
to use the Sybase ORB if I can.

Thanks

Glenn

Why do you need the gateway?

The Sybase ORB provides automatic HTTP-tunneling of IIOP, with no gateways and
no configuration.

That's a good thing, but our Jag server is behind a firewall and our
systems administrator is not too keen on letting it listen to traffic
from the outside. Hence the 'need' for a gateway between our webserver
and Jag. (Unless I can convince sysadm to let Jag listen to outside
world...) Suggestions?

Get your sysadm to open a hole in the firewall that allows TCP traffic only
to port 9000 on your Jaguar host. Since in the end the client requests have to
be routed to the Jaguar server, nothing is gained by having a gateway sitting
in between client and Jaguar server.

There is also a set of proxy properties you can set before calling ORB.init,
if indeed you do need the client to re-route requests through a third-party
gateway or proxy server.

Let me find out exactly what her concerns are, and then I'll post
questions that she may have.
